CENTRIFUGAL LIQUID-SEPARATOR.

SPECIFICATION formingpart Yof Letters Patent No. 6163,111, dated December 4, 1900.

i Application filed October 22,1898. Serial No. 694,250I (No model.)

To all whom t may concern:

Be it known that I, JOHN JOSEPH BEREI- GAN, a citizen of the United States, residing at Avon, county of Livingston and State of New York, have invented a new and useful Improvement in Centrifugal Liquid-Separatore, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form,a part of this specilication.

My invention has for its object certain improvements in that class of liquid centrifugal separators in which in the liquid-space of the bowl there are a series of curved upright blades which intersect the radial line of the bowl and to provide such construction of this class of machines as will permit the ready insertion of these blades inthe bowl and .removal therefrom and also such construction i as will enable them to be readily cleaned. To

that end I make each blade separate and independent of the other and insert them in the bowl in such manner that while in as well as out of the bowl they are separate and independent of one another and yet while in the bowl are maintained in proper relation to each other and as an entiretyare in proper position in the bowl.

The underlying idea of my invention is the independent separate blades as the mechanism for properly supporting them with relation to each other and as a whole in proper position in the bowl may be varied in many Ways.

In the drawings I have shown several em bodiments of my invention, and I will now describe what is therein shown.

Figure l is a'plan View of a bowl and blades with the cover removed. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a detail View of bowl and lug for securing blades. Fig. 4 is a view similar to Fig. l of modified form. Fig. 5 is a section on the line 5 5 of Fig. 5. Fig. 6 is a detail view of tubular shaft and ring having a lug' for securing the ring. Fig. 7 is a view similar to Fig. l of modified form. Fig. 8 is a section on the line 8 8 of Fig 7 Fig. 9 is a plan View similar to Fig. l of a modiied form. Fig. 10 is a section on the line 10 10 of Fig. 9.

The drawings show a liquid centrifugal separator adapted for the separation of cream from milk.

Taking first Figs. l and 2, Ais the bowl, and a the neck of the cover of the bowl. B is the tubular shaft for feeding in Vfull milk, b the cream-outlet, and b the skim-milk outlet. O represents a series of curved upright blades which may be provided with spacing projections c. Secured to the inner peripheral wall of the bowl is a ring D, secured to the bowl by the spurs or lugs d. This ring has a series of grooves d', into which grooves the outer ends of the independent upright curved blades are placed, the spacing projections c keeping them apart. If desired, instead of a ring a lug d4, projecting from the inner Wall of the bowl, maybe grooved and one of the-blades secured therein, the remaining plates being set in place loosely against this plate. The blades extending all around the bowl, this plate will maintain the blades as a whole in proper position'. This is shown in Fig. 3. In either case the blades are inserted as described, with the cover removed, and then the cover is put in piace. N is a flange projecting from the tubular shaft B, against which the inner ends of the blades rest and by which lthe position of their inner end is maintained.

In Figs. 4 and 5 the diiference in construction over that of Figs. l and 2 consists in the partcorresponding to ring D, which is denoted by the letter E and, like ring D, is a ring provided with grooves, is placed in the central portion of the bowl connected to the tubular shaft, and the inner ends of the curved upright blades are placed in these grooves. As in the construction shown in Fig. 3, a grooved lug e may be substituted for the ring E andone of the blades secured therein, the remaining blades built thereon as in this figure. This is shown in Fig. 6.

In Figs. 7 and 8 I have shown a construction similar to Fig. 2, but in which the tubular shaft is removed and the position of the inner ends of the blades determined by an annular ange F, secured to the bottom of the bowl.

In Figs. 9 and l0 the construction is similar to the preceding Figs. 7 and 8, except that the grooved flange for the reception of one of the blades is placed on the bottom of IOO the bowl, as shown at G, and the position of the inner ends of the blades is determined by flanged ring I-I, placed in the upper central portion of the bowl.

From the preceding description ofthe draw ings it is clear that the construction which determines the relative position of the blades with reference to each other and as a whole with reference to the bowl may be varied in many ways, and I do not, except as hereinafter claimed, intend to limit myself to the means illustrated and described nor to any particular means. y

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-

l. In a centrifugal liquid-separator, in combination, a plurality of independent separate upright blades intersecting the radial line, a notched surface the blades being adapted to be supported by said notched surface, and means to maintain the inner end of the blades.

2. .In a centrifugal liquid-separator, in combination, a plurality of independent separate upright blades intersecting the radial line of the bowl, a surface provided with notches equal in number to the blades and in which the blades are adapted to be placed and held.

3.l In a centrifugal liquid-separator, in com` bination, a plurality of independent separate upright blades intersecting the radial line of the bowl, a surface provided with notches equal in number to the blades and in which the blades are adapted to be placed and held, and means to maintain the inner ends of the blades in position.

4. ln acentrifugal liquid-separator, in combination, a plurality of independent separate curved upright blades intersecting the radial line of the bowl, a notched surface the blades beingadapted to be supported by said notched surface.

5. In acentrifugal liquid-separator, in combination, a plurality of independent separate curved upright blades intersecting the radial line, a notched su rface the blades being adapted to be supported by said notched surface, and means to maintain the inner end of the blades in position.

6. In a centrifugal liquid-separator, in combination, a plurality of independent separate curved upright blades intersecting the radial line of the bowl, a surface provided with notches equal in number to the blades and in which the blades are adapted to be placed and held.

7. In a centrifugal liquid-separator, in combination, a plurality of independent separate curved upright blades intersecting the radial line of the bowl, a surface provided with notches equal in number to the blades and in which the blades are adapted to be placed and held, and means to maintain the inner ends ofthe blades in position.

In testimony of which invention I have hereunto set my hand, at Philadelphia, Pennsylvania, on this 30th day of September, 1898.

JOHN JOSEPH BERRIGAN.
